| Sumario: | The antibiotic resistance phenotype of bacteria colonizing canine pets was characterized. One hundred domestic dogs from kennels were sampled. Bacterial identification and sensitivity testing was performed using the VITEK® 2 system, and phenotypes were confirmed according to the Clinical and Laboratory Standards Institute (CLSI) methodology. A total of 408 microorganisms were isolated, of which 57% were Enterobacteriaceae, 23% Staphylococcus, 10% non-fermenting Gram-negative bacilli, and 5% enterococci. Moreover, 80% of Staphylococcus strains were methicillin-resistant, E. faecalis was the only bacterium of its genus to exhibit resistance to gentamicin and vancomycin, 57% of Enterobacteriaceae were β-lactamase producers, while 10% of non-fermenting Gram-negative bacilli were carbapenemase-positive. The characterization of the antibiotic resistance phenotype in bacteria colonizing canine pets revealed a worrying prevalence of multidrug-resistant strains. These results highlight the need for ongoing and rigorous monitoring of antibiotic resistance in pets. |
